首先肯定是引头文件了

import Alamofire

GET请求

不含参数

Alamofire.request(.GET, "http://httpbin.org/get")

         .response { (request, response, data, error) in
                     println(request)
                     println(response)
                     println(error)

        "z": 3
    ]

                  parameters: parameters)

Download File

Alamofire.download(.GET,
                  "http://httpbin.org/stream/100",
                  destination: { (temporaryURL, response) in
    if let directoryURL = NSFileManager.defaultManager()
                          .URLsForDirectory(.DocumentDirectory,
                                            inDomains: .UserDomainMask)[0]
                          as? NSURL {
        let pathComponent = response.suggestedFilename
 
        return directoryURL.URLByAppendingPathComponent(pathComponent)
    }
 
    return temporaryURL
})

Upload file

let fileURL = NSBundle.mainBundle()
                      .URLForResource("Default",
                                      withExtension: "png")

                 file: fileURL)

下载图片

Alamofire.request(.GET, "/article/image/20150128/54c85e49bfa8d25764000f47/small_f3338d9cdf932cc3c0464dcb523361c5.jpg").response() {(_, _, data, _) in
            let image = UIImage(data: data! as NSData)
            self.imageView.image = image
        }
